Software Engineering Testing MCQ Questions
Q1. Boundary value analysis and equivalence partitioning are used because:
A. They are not effective
B. They are identification of faults
C. They are central to Functional Testing
D. None of these
View Answer
Answer: C
Explanation: These are classic black-box testing techniques used to design test cases based on input conditions without knowing internal code.
Q2. In data-flow testing, the objective is to find:
A. All du-paths that are not dc-paths
B. All du-paths (definition-use paths)
C. All dc-paths that are not du-paths
D. All dc-paths
View Answer
Answer: B
Explanation: Data-flow testing focuses on tracking variables from definition to usage to ensure proper data handling.
Q3. The overhead code required to be written for unit testing is called:
A. Drivers
B. Stubs
C. Scaffolding
D. None of these
View Answer
